Letters .Patent Illa-95,149, dated September 421, 1869.

The'sohedule referred to in these Letters Patent and making part ,of the same.

To all whom it may concern-f: ,p

' Be it known that I, ANDREAS ScHoPr,of Belle- 4ville,-in the county of St. Clair, and State of Illinois,

have made certain new and useful Improvements in Seed-Feedin g Devices for Grain-Drills; and I do hercby declare thcfellowiug to be a full and true description thereof, reference being had to the accompanying drawings, and tothe-letters of reference marked thereon the use of aV grooved Wheel, whereon the grain isleceived, and-which, in revolving, carries the same to a discharge, in connection with a regulating-slideand a vibrating finger, the former to gauge the quantity of` grain discharged, the other to cause the grain. to drop gradually and regularly into the feed-passage, and prevent clogging.

. To enable those herein skilled to make and use my said improvemen' will now morel fully describe the same, referring to the accompanying- Figure 1 as a` longitudinal section; to lFigure 24 as a plan; and to i Figure 3 as a transverse section, showing the s'aid sleed-ieedin g device as adapted for one linke of a grainc rill.

In saidgures, A represents the seed-box, wherein grain is'deposited. Said ,box usually'rests upon Vthe frame of a grain-drill, over the `luke's.

In the bottom 'of saidbox is a seed-passage, a, 'the' available `opening whereof is regulated by a slide, B, which may be connected in suchwise with the ukes .that when these. are raisedout of ground, it will be closed, to check the passage of seed out ofthe box.

Under said opening a, Iarrange'the distributing` wheel '0, upon a shaft, O', which runs transversely across the frame of the grain-drill, andis supportedin proper bearings.

The wheel O has a continuous groove, c, being herein dissimilar to many ofthe distributing-wheels nowin `common use'. The Vseed dropsA4 into said groove, and, as the wheel is revolved, the seed is carried back, to y drop into the funnels leadingl to the ilukes. Y

.l llhis inveutiurelates to the devices generallyused` for-distributing or feeding grain 'to the lukes or shoes To regulate the quantity passing intothe groove e, I apply the slide D, which dips more or less into saidl groove, as ,n accordance with its puosition, and which is lieldto its adjustedposition by a'set-screw, d.

In order that the seed shall not clog the opening a, and especially to prevent straw or dust from clogging said opening, I arrange a vibrating fnger, E, upon' a shaft, E', said finger being vibrated 'to clear said opening from obstruction by the movement of its shaft.

lhe shaftj-El will vbe supported in the ends of the seed-box, and this shaft, as well as the shaft C', will be operated from the usual driving-wheel of the drill,` orlfrom any other power-source, which, by an ordinary spur-wheel, drives thewheel F upon the shaft C', to' revolve said shaft. 1 l

An intermediate wheel, `frgears into .the Wheellir and is supported, by itsaxle, on the seed-box.

A connecting-rod, g, connects said wheel f with the crank G, which is upon the `outer end of the shaft E',

` and which thus acts to vibratethe shaft as required.

In the grain-drill where there are usually seven `or eight linkes, and as many distributing-devices, it will be advisable to connect the several slidesD of all the seed-distributers in snchwise that they may be oper- `ated simultaneously.

`The slide D will be arranged nearly or`quite in the vertical plane of the axis ofthe shaft C. If, therefore, the movementof the'shaft C ceases, (as when the grain-drill standsv still,) the seed will be simply in the groove c,but, not being carried back, Will not fall to the linkes. Thus the device, in a simple and effective manner, is arranged to meet the variousrequrernents of a good seed-feeding machine. Again, -as the seed is not confined int small cavities which pass closely under a honsing`or edge, as in many so-called forcefeed devices, it is plain that the seed-kernels here will not becut or'broken, and thus rendered useless.

Having thus fully described pixy said invention,

What I claim, is- The distributing-wheel C, arranged with continuous groove, andl combined with the regulating-slide D, substantially as set forth.
